Intra-Configurational Spin-Flip d → $ \to $ d Transition of Mo (III) Doped Perovskite for Ultra-Narrow Near Infrared-II Emission in Ambient Conditions.

Sharp near-infrared-II (NIR-II) emissions are typically achieved through f → f $f \to f$ electronic transitions of rare-earth ions, while d → d $d \to d$ transitions in transition metal ions are broad due to electron-ligand interactions. An excep…
